सत्त्वं सुखे संजयति रजः कर्मणि भारत । ज्ञानमावृत्य तु तमः प्रमादे संजयत्युत ॥९॥
sattvaḿ sukhe sañjayati rajaḥ karmaṇi bhārata jñānam āvṛtya tu tamaḥ pramāde sañjayaty uta
sattvam — the mode of goodness; sukhe — in happiness; sañjayati — binds; rajaḥ — the mode of passion; karmaṇi — in fruitive activity; bhārata — O son of Bharata; jñānam — knowledge; āvṛtya — covering; tu — but; tamaḥ — the mode of ignorance; pramāde — in madness; sañjayati — binds; uta — it is said.
Sattva binds one to material happiness; rajas conditions the soul toward actions; and tamas clouds wisdom and binds one to delusion.
A person in the mode of goodness is satisfied by his work or intellectual pursuit, just as a philosopher, scientist or educator may be engaged in a particular field of knowledge and may be satisfied in that way. A man in the mode of passion may be engaged in fruitive activity; he owns as much as he can and spends for good causes. Sometimes he tries to open hospitals, give to charity institutions, etc. These are signs of one in the mode of passion. And the mode of ignorance covers knowledge. In the mode of ignorance, whatever one does is good neither for him nor for anyone.
